Description

本発明は、請求項１の上位概念に記載のカッタに関する。  The present invention relates to a cutter according to the superordinate concept of claim 1.

このようなカッタはドイツ連邦共和国特許第３６２２３４３号明細書から公知である。公知のカッタはハウジングを持ち、このハウジング内に摺動体部分が移動可能に案内されている。摺動体部分はカバーを持ち、摺動体部分の本体とカバーとの間にカッタ刃が保持されている。摺動体部分を操作するため、ハウジングの側方に摺動体縦スリットが設けられている。摺動体部分の不使用位置においてカッタ刃が、摺動体縦スリットを通して摺動体部分へ挿入可能であり、この摺動体部分のカバーが刃送り方向に対して直角にかつ握り体の横軸線に対して平行に外方へ揺動可能である。カバーは同時に摺動体部分用の操作素子を形成している。  Such a cutter is known from DE 3622343. A known cutter has a housing in which a sliding body portion is guided so as to be movable. The sliding body portion has a cover, and a cutter blade is held between the main body of the sliding body portion and the cover. In order to operate the sliding body portion, a sliding body longitudinal slit is provided on the side of the housing. The cutter blade can be inserted into the sliding body part through the sliding body vertical slit at the non-use position of the sliding body part, and the cover of this sliding body part is perpendicular to the blade feed direction and to the horizontal axis of the grip body It can swing outward in parallel. The cover simultaneously forms an operating element for the sliding part.

その他の点で有利なこのカッタは、カッタの構造に限界があるという点で、改善の余地がある。特に刃を通すことができるようにするため、刃を交換するための摺動体縦スリットを適当な大きさに構成せねばならない。刃交換の際取扱いに関しても、刃は改善の余地がある。  This other advantageous cutter has room for improvement in that the cutter structure is limited. In particular, in order to be able to pass the blade, the sliding body longitudinal slit for exchanging the blade must be configured to an appropriate size. There is room for improvement in blades when handling blades.

先にあげた従来技術か出発して本発明の課題は、高い動作安全性で取扱いを改善されているカッタを提供することである。  Starting from the prior art mentioned above, the object of the present invention is to provide a cutter with improved operational safety and improved handling.

この課題は、請求項１の特徴特にその特徴部分によって解決される。  This problem is solved by the features of claim 1, in particular by its features.

本発明の重要な原理は、操作突起が刃留め具外で本体に保持され、それにより刃取付け具に隣接する収容通路の内面が、刃留め具用制御面として役立つことである。刃取付け具の不使用位置又は動作位置で、収容通路の内面が刃留め具を閉鎖位置に保持する。しかし刃留め具がカッタ通過開口を通って前外方へ刃交換位置へ移動している時、刃取付け具の少なくとも１つの部分範囲が収容通路の内面との接触を失うので、刃留め具の開放及びカッタ刃の取出しが可能である。  An important principle of the present invention is that the operating projection is held on the body outside the blade fastener so that the inner surface of the receiving passage adjacent to the blade fixture serves as a control surface for the blade fastener. In the unused or operating position of the blade fixture, the inner surface of the receiving passage holds the blade fastener in the closed position. However, when the blade fastener is moved forward and outward through the cutter passage opening to the blade replacement position, at least one partial area of the blade attachment loses contact with the inner surface of the receiving passage, Opening and removal of the cutter blade are possible.

本発明は、刃の交換を非常に簡単に行うことができるという著しい利点を持っている。カッタハウジングの形成自由度は著しく高まる。本発明による解決策によって、ハウジングに摺動体縦スリットを設け、このスリットを通して刃の交換を行うことは、もはや必要でない。操作突起用の非常に小さい開口のみを設けることを可能にし、それにより汚物がここを通ってカッタハウジングへ侵入するのが防止される。  The present invention has the significant advantage that the blade can be replaced very easily. The degree of freedom of forming the cutter housing is significantly increased. With the solution according to the invention, it is no longer necessary to provide a sliding body longitudinal slit in the housing and to exchange the blades through this slit. It is possible to provide only a very small opening for the operating projection, thereby preventing dirt from entering the cutter housing therethrough.

第１の実施形態によれば、操作突起がカッタ通過開口から遠い方にある側で本体に保持されている。操作突起は、カッタ通過開口に対向している刃取付け具の幅狭い側に取付けることができる。こうして収容通路の内面は、刃取付け具の外面用の案内兼制御面として役立つ。  According to the first embodiment, the operation protrusion is held by the main body on the side farther from the cutter passage opening. The operating projection can be attached to the narrow side of the blade fixture facing the cutter passage opening. The inner surface of the receiving passage thus serves as a guide and control surface for the outer surface of the blade fixture.

別の実施形態によれば、刃留め具の揺動可能な配置により、本体からの揺動が可能であり、刃留め具に本体に常に失われないように保持されている。更に揺動可能な配置は、刃留め具をカッタハウジングの収容通路から完全に出す必要なしに、刃の交換を可能にする。  According to another embodiment, the swingable arrangement of the blade fastener allows it to swing from the main body and is held by the blade fastener so that it is not lost to the main body at all times. Furthermore, the swingable arrangement allows the blades to be replaced without having to completely remove the blade fastener from the cutter housing receiving passage.

本発明の別の構成によれば、刃留め具の揺動軸線が刃取付け具の移動方向に対して直角に設けられている。揺動軸線のこの配置では、刃留め具の部分範囲のみを収容通路から出せば充分である。その場合刃留め具は、特定の角度だけ揺動可能であり、刃交換が行われる範囲まで、刃取付け具の前部範囲にある刃留め具が本体から離れている。  According to another configuration of the invention, the swing axis of the blade fastener is provided perpendicular to the direction of movement of the blade fixture. With this arrangement of the pivot axis, it is sufficient to leave only a partial area of the blade fastener from the receiving passage. In that case, the blade fastener can be swung by a specific angle, and the blade fastener in the front range of the blade mounting tool is separated from the main body to the extent that the blade is replaced.

別の実施形態によれば、刃留め具の揺動軸線が刃取付け具の移動方向に対して平行に設けられている。その場合刃留め具は、収容通路から刃留め具を完全に出した後に初めて、本体から離すことができる。  According to another embodiment, the swing axis of the blade fastener is provided parallel to the direction of movement of the blade fixture. In this case, the blade fastener can be separated from the main body only after the blade fastener is completely removed from the receiving passage.

本発明の別の構成によれば、刃留め具がその隣接する外面に対して突出する接触素子を持ち、この接触素子の外面が、カッタの不使用位置及び切断位置で、刃留め具を本体に保持するように、収容通路の内面と共同作用し、刃交換位置で外面が、収容通路の内面とは接触しない。接触素子はカッタハウジングの内面と一致し、従って不使用位置及び切断位置において、刃留め具を本体に密接して保持し、刃交換位置において接触素子は、もはやカッタハウジングの内面によって案内されず、従って刃留め具の揺動が可能にされる。  According to another configuration of the present invention, the blade fastener has a contact element projecting against its adjacent outer surface, and the outer surface of the contact element is in a non-use position and a cutting position of the cutter, and the blade fastener body So that the outer surface does not contact the inner surface of the housing passage at the blade replacement position. The contact element coincides with the inner surface of the cutter housing and thus holds the blade fastener in intimate contact with the body in the non-use position and the cutting position, in which the contact element is no longer guided by the inner surface of the cutter housing, Accordingly, the blade fastener can be swung.

本発明の別の構成によれば、接触素子が刃取付け具の前端部に設けられている。この実施形態により、本体から刃留め具を広げて刃の交換を可能にするため、刃取付け具を僅かな寸法だけ収容通路か出せばよい。  According to another configuration of the invention, the contact element is provided at the front end of the blade fixture. According to this embodiment, in order to spread the blade fastener from the main body and enable the replacement of the blade, the blade mounting tool has to be taken out of the receiving passage by a small size.

別の実施形態によれば、刃留め具又は収容通路の内面がレバー素子を持ち、刃交換位置でレバー素子が刃留め具を本体から広げるように、収容通路に付属する相手面又は刃留め具の内面と共同作用する。この実施形態によっても、ばね素子を節約することができる。保持素子が収容通路の内壁範囲に当たることにより、レバー作用によって、刃交換位置にある刃留め具が自動的にその開かれる位置へ揺動される。  According to another embodiment, the inner surface of the blade fastener or receiving passage has a lever element, and the mating surface or blade fastener attached to the receiving passage so that the lever element spreads the blade fastener from the body at the blade replacement position. Synergistic with the inner surface of. This embodiment also saves the spring element. When the holding element hits the inner wall area of the receiving passage, the blade fastener in the blade replacement position is automatically swung to the opened position by lever action.

別の実施形態によれば、レバー素子がほぞにより形成され、相手面が傾斜路状溝底を持つ溝により形成されている。不使用位置及び切断位置において、ほぞが傾斜路の一層高い範囲に当接して、本体から刃留め具が広がるのを防止する。これに反し刃交換位置では、ほぞは一層深い傾斜路範囲へ動いている。従って刃留め具は、本体から離すのに充分な空間を持っている。ほぞは刃交換位置で溝範囲の側壁に当たり、刃留め具を本体から広げる。  According to another embodiment, the lever element is formed by a tenon and the mating surface is formed by a groove having a sloped groove bottom. In the non-use position and the cutting position, the tenon contacts the higher range of the ramp to prevent the blade fastener from spreading from the body. On the other hand, in the blade replacement position, the tenon moves to a deeper ramp range. Accordingly, the blade fastener has sufficient space to be separated from the main body. The tenon hits the side wall of the groove range at the blade replacement position and spreads the blade fastener from the main body.

別の実施形態によれば、レバー素子が刃留め具に結合される腕により形成され、相手面が収容通路に付属するストッパ面の内面により形成されている。腕は刃留め具と物質的に一体に結合可能である。刃交換位置で腕は、例えばカッタハウジングのストッパ面に当たって、刃留め具の揺動を行うので、刃留め具が本体から広がる。  According to another embodiment, the lever element is formed by an arm coupled to the blade fastener and the mating surface is formed by an inner surface of a stopper surface attached to the receiving passage. The arm is materially connectable with the blade fastener. At the blade replacement position, for example, the arm hits the stopper surface of the cutter housing and swings the blade fastener, so that the blade fastener spreads from the main body.

本発明の別の構成によれば、刃交換位置への刃取付け具の運動が、安全位置と釈放位置との間で可動な安全素子により阻止可能である。安全素子により、刃交換位置への移動を防止できる。それにより刃交換位置への予期しない移動の危険なしに、カッタによる安全な作業が可能である。安全素子は、例えばレバーに付属するストッパにより形成することができる。その場合揺動により、ストッパ素子は、刃取付け具の運動軌道へ入るか又は運動軌道から出ることができる。ストッパ素子が刃取付け具の運動軌道にあると、刃取付け具を切断位置へのみ動かすことができる。これに反しストッパ素子が刃取付け具の運動軌道から出るように動いていると、刃取付け具が刃交換位置へ移動可能である。  According to another configuration of the invention, movement of the blade fixture to the blade replacement position can be prevented by a safety element movable between a safe position and a release position. The safety element can prevent movement to the blade replacement position. As a result, it is possible to perform a safe operation with the cutter without risk of unexpected movement to the blade replacement position. The safety element can be formed by a stopper attached to the lever, for example. In this case, by rocking, the stopper element can enter or leave the movement track of the blade fixture. If the stopper element is in the movement path of the blade fixture, the blade fixture can only be moved to the cutting position. On the other hand, when the stopper element is moved so as to come out of the movement track of the blade mounting tool, the blade mounting tool can be moved to the blade replacement position.

本発明の別の構成によれば、刃取付け具が、刃留め具を開放方向に負荷するばね素子を持っている。従って刃交換位置において刃留め具が、ばね素子により自動的に本体から離される。  According to another configuration of the invention, the blade fixture has a spring element that loads the blade fastener in the opening direction. Accordingly, the blade fastener is automatically separated from the main body by the spring element at the blade replacement position.

別の実施形態によれば、刃留め具が弾性材料により形成され、この材料のばね弾性の戻し力が刃留め具を開放方向に負荷する。従って付加的なばね素子を設ける必要がない。刃留め具が本体に当接すると、刃留め具の材料が変形され、刃交換位置で刃留め具から負荷が除かれるので、刃留め具から離れる。  According to another embodiment, the blade fastener is formed of an elastic material, and the spring-elastic return force of this material loads the blade fastener in the opening direction. Therefore, there is no need to provide an additional spring element. When the blade fastener comes into contact with the main body, the material of the blade fastener is deformed, and the load is removed from the blade fastener at the blade replacement position, so that the blade fastener moves away.

本発明のそれ以外の利点は、引用されなかった従属請求項及び図面に示されている実施例の以下の説明から明らかになる。  Other advantages of the present invention will become apparent from the dependent claims which have not been cited and the following description of the embodiments shown in the drawings.

図面においてカッタは、全体を符号１０で示されている。異なる図において小文字を補足しても、同じ符号は一致する部分を示している。  In the drawing, the cutter is indicated by the reference numeral 10 as a whole. Even if lowercase letters are supplemented in different drawings, the same reference numerals indicate corresponding parts.

このようなカッタ１０は、図１によれば、大体においてカッタハウジング１１、刃１３を持つ刃取付け具１２、及び操作突起１４を持っている。カッタハウジング１１は２つのハウジング部分１１ａ及び１１ｂから成り、見易くするため、図１にはハウジング部分１１ａのみが示されている。  According to FIG. 1, such a cutter 10 generally has a cutter housing 11, a blade fixture 12 having a blade 13, and an operation projection 14. The cutter housing 11 comprises two housing parts 11a and 11b, and for the sake of clarity, only the housing part 11a is shown in FIG.

操作突起１４は弓形片状に形成され、弓形片自由端３２ａ及び３２ｂは橋絡片４０により結合されている。操作突起１４の橋絡片４０は、刃取付け具１２の後端部３９に取付けられている。弓形片自由端３２ａ及び３２ｂは、ハウジング部分１１ａの開口３３ａ及びハウジング部分１１ｂの開口３３ｂから突出している。従って操作突起１４は、カッタ１０を右手でも左手でも使用可能にする。  The operation protrusion 14 is formed in an arcuate piece shape, and the arcuate piece free ends 32 a and 32 b are connected by a bridging piece 40. The bridging piece 40 of the operation protrusion 14 is attached to the rear end portion 39 of the blade attachment 12. The arcuate piece free ends 32a and 32b protrude from the opening 33a of the housing part 11a and the opening 33b of the housing part 11b. Therefore, the operation protrusion 14 enables the cutter 10 to be used with either the right hand or the left hand.

刃取付け具１２は、カッタハウジング１１の収容通路Ａ内に並進移動可能に収容されている。収容通路は、大体においてハウジング部分１１ａ及び１１ｂの内面３５ａ及び３５ｂにより区画されている。図６による不使用位置から始まって、刃取付け具１２は、図示してないが一端をハウジング１１に直接取付けられかつ他端を刃取付け具１２に取付けられる２つの渦巻きばね２４ａ，２４ｂの力に抗して、図６による不使用位置から、図１〜５による切断位置へ移動可能である。図５に示すように、刃取付け具１２のかぎ突起１５が傾倒レバー１７のストッパ素子（安全素子）１６に当たると、切断位置が得られる。こうしてストッパ素子１６は、刃取付け具１２が切断位置を越えて方向ｘ１へ動かされるのを防止する。切断位置において刃１３は、カッタハウジング１１のカッタ通過開口３７を貫通している。The blade attachment 12 is accommodated in the accommodation passage A of the cutter housing 11 so as to be capable of translational movement. The housing passage is roughly defined by the inner surfaces 35a and 35b of the housing portions 11a and 11b. Starting from the non-use position according to FIG. 6, the blade fixture 12 is subjected to the force of two spiral springs 24 a, 24 b, not shown, with one end attached directly to the housing 11 and the other end attached to the blade fixture 12. On the contrary, it is possible to move from the non-use position according to FIG. 6 to the cutting position according to FIGS. As shown in FIG. 5, when the hook projection 15 of the blade fixture 12 hits the stopper element (safety element) 16 of the tilting lever 17, the cutting position is obtained. Thus the stopper element 16 prevents the cutting fixture 12 is moved beyond the cutting position in the direction x 1. In the cutting position, the blade 13 passes through the cutter passage opening 37 of the cutter housing 11.

図４によれば、刃１３は、刃取付け具１２の本体Ｇの壁範囲１８の内面３８と、刃取付け具１２に揺動可能に取付けられる刃留め具１９の内面３１との間に、摩擦及びはまり合いで保持されている。図２によれば、壁範囲１８はほぞ２０を持ち、このほぞ２０が刃１３の切欠き２１をはまり合いで貫通している。刃１３の摩擦及びはまり合い取付けの際二重はめ合いを回避するため、刃留め具１９はほぞ２０用切欠き２２を持っている。  According to FIG. 4, the blade 13 has a friction between the inner surface 38 of the wall region 18 of the body G of the blade fixture 12 and the inner surface 31 of the blade fastener 19 that is pivotably attached to the blade fixture 12. And held together. According to FIG. 2, the wall area 18 has a tenon 20 which fits through the notch 21 of the blade 13. The blade fastener 19 has a tenon 20 notch 22 to avoid double mating during blade 13 friction and mating installation.

刃留め具１９は前端部３６にカラー３４を備えている。カラー３４の接触面２３は、図６による不使用位置及び図１〜５による切断位置で、またその間にある刃取付け具１２のすべての位置で、カッタハウジング部分１１ｂの内面３５ｂに当接し、それにより刃留め具１９が刃取付け具１２の本体Ｇから方向ｙ１に広がるのを防止している。刃の交換は次のように行うことができる。The blade fastener 19 has a collar 34 at the front end 36. The contact surface 23 of the collar 34 abuts the inner surface 35b of the cutter housing part 11b in the non-use position according to FIG. 6 and the cutting position according to FIGS. 1-5 and at all positions of the blade fixture 12 between them. cutting the fastener 19 is prevented from spreading in the direction y 1 from the body G of the blade fixture 12 by. The blade can be replaced as follows.

傾倒レバー１７を揺動軸線ａの周りに揺動することにより、傾倒レバー１７のストッパ素子１６を、刃取付け具１２のかぎ突起１５の運動軌道から出るように動かすことができる。それにより刃取付け具１２を、図１〜５による切断位置を越えて、図７〜９による刃交換位置へ動かすことができ、その際カラー３４が収容通路Ａから出て、カッタハウジング部分１１ｂの内面３５ｂには接触しなくなる。  By swinging the tilt lever 17 around the swing axis a, the stopper element 16 of the tilt lever 17 can be moved out of the movement track of the hook projection 15 of the blade fixture 12. As a result, the blade fixture 12 can be moved beyond the cutting position according to FIGS. 1 to 5 to the blade replacement position according to FIGS. 7-9, at which time the collar 34 exits the receiving passage A and moves into the cutter housing part 11b. It will not contact the inner surface 35b.

刃交換位置で、縦軸線に対して鋭角をなして物質的に一体に刃留め具１９に設けられているレバー腕２５が、カッタハウジング１１ｂのストッパ面２８に当たり（図９参照）、それによりその揺動軸線ｂの周りに方向ｙ１へ、刃留め具１９の外壁２６が内面３５ｂに当接するまで、刃留め具１９を回転させる。その際刃留め具１９が本体Ｇの壁範囲１８から角αだけ揺動されて、刃１３をほぞ２０から外して刃交換を行うのを可能にする。At the blade replacement position, the lever arm 25 provided on the blade fastener 19 materialically and integrally with an acute angle with respect to the longitudinal axis hits the stopper surface 28 of the cutter housing 11b (see FIG. 9), thereby the direction y 1 about the pivot axis b, the outer wall 26 of the blade fastener 19 until it abuts against the inner surface 35b, rotating the blade clamp 19. At that time, the blade fastener 19 is swung from the wall region 18 of the main body G by an angle α to allow the blade 13 to be removed from the tenon 20 and to be replaced.

刃交換を行った後、操作突起１４へ作用する力をなくすことにより刃取付け具１２は渦巻きばね２４により方向ｘ２にハウジング１１内へ戻される。方向ｘ２への運動のため、レバー腕２５はもはやカッタハウジング１１のストッパ面２８に当接しないので、刃留め具１９は方向ｙ２に戻り揺動することができる。After blade replacement, the blade fixture 12 by eliminating the force acting on the operating projection 14 is returned into the housing 11 in the direction x 2 by spiral spring 24. For movement in the direction x 2, does not abut against the stopper surface 28 of the lever arm 25 is longer cutter housing 11, the blade fasteners 19 can be swung back in the direction y 2.

方向ｘ２へ刃取付け具１２を戻す際、カッタハウジング１１の前縁３０と共同作用するカラー３４の斜面２９により、刃留め具１９の閉鎖が促進されるので、刃留め具１９の内面３１が再び本体Ｇに当接するまで、力が閉鎖方向ｙ２に刃留め具１９へ作用する。刃１３は再び刃留め具１９の内面と本体Ｇの内面３８との間に固定的に保持される。ハウジング１１内へ刃取付け具１２を更に戻すことにより、突起３４の接触面２３が再びカッタハウジング部分１１ｂの内面３５ｂと接触するので、刃留め具１９の開放が防止される。When returning cutting fixture 12 in the direction x 2, the inclined surface 29 of the collar 34 which cooperates with the leading edge 30 of the cutter housing 11, the closure of the blade fastener 19 is promoted, the inner surface 31 of the blade fastener 19 until it abuts against the body G again force is applied to the cutting fastener 19 in the closing direction y 2. The blade 13 is again held fixedly between the inner surface of the blade fastener 19 and the inner surface 38 of the main body G. By further returning the blade fixture 12 into the housing 11, the contact surface 23 of the projection 34 again contacts the inner surface 35b of the cutter housing portion 11b, thereby preventing the blade fastener 19 from being opened.

刃取付け具１２が図６による不使用位置へ動かされた後、傾倒レバー１７が再び図１〜５による位置へ戻り揺動でき、ストッパ素子１６が再びかぎ突起１５の運動軌道へ入る。従って刃取付け具１２は、もはや切断位置を越えて方向ｘ１へ動かされることはない。After the blade fixture 12 is moved to the non-use position according to FIG. 6, the tilting lever 17 can return and swing back to the position according to FIGS. 1 to 5, and the stopper element 16 again enters the movement track of the hook projection 15. Thus cutting fixture 12 is never moved in the direction x 1 beyond the longer cutting position.
